To use randomColor in the browser, download the latest minified version of randomColor and include it on your page. Then call the script:
var color = ; // a hex code for an attractive color
To use randomColor on the server with node.js, install randomColor from npm then call the script:
npm install randomcolor
var randomColor = ; // import the scriptvar color = ; // a hex code for an attractive color
You can pass an options object to influence the type of color it produces. The options object accepts the following properties:
hue – Controls the hue of the generated color. You can pass a string representing a color name:
monochrome are currently supported. If you pass a hexidecimal color string such as
#00FFFF, randomColor will extract its hue value and use that to generate colors.
luminosity – Controls the luminosity of the generated color. You can specify a string containing
count – An integer which specifies the number of colors to generate.
seed - An integer or string which when passed will cause randomColor to return the same color each time.
format – A string which specifies the format of the generated color. Possible values are
alpha – A decimal between 0 and 1. Only relevant when using a format with an alpha channel (
hsla). Defaults to a random value.
// Returns a hex code for an attractive color;// Returns an array of ten green colors;// Returns a hex code for a light blue;// Returns a hex code for a 'truly random' color;// Returns a bright color in RGB;// Returns a dark RGB color with random alpha;// Returns a dark RGB color with specified alpha;// Returns a light HSL color with random alpha;
More generally, it might be a good idea to consider using other color models.
- use this on the demo http://jsfiddle.net/dpLp318f/ https://www.vis4.net/blog/posts/avoid-equidistant-hsv-colors/ https://www.vis4.net/blog/posts/mastering-multi-hued-color-scales/
- When returning an array of multiple colors, try to make each color as distinct as possible. Make sure each color is distinct to its neighbours.
- Improve attractive dark color generation, currently they're a touch murky.
- Improve the color dictionary
- definition of hue values and attractive luminosity bounds
- think about how to store hue aliases (e.g. fuschia) or subranges (e.g teal)
- think about making a little point and click tool for defining your own luminosity bounds and customizing the color dictionary
- Think about how to return seeds.
- Think about adding feature to return complementary & contrasting colors, as well as color triads, tetrads etc. Other libraries might already do this better though.
- Think about adding a scheme options which would return a dominant color, as well as secondary, tertiary color and primary and secondary text colors. This might be a bad idea.
- Add a nice visualization of the 'attractive color space' to the demo https://www.youtube.com/watch?v=x0-qoXOCOow
- Add a feature to return random colors close to a provided hex
